CAP-SPINDLE.

SPECIFICATION forming part of Letters Patent No. 633,302, dated SeptembervlQ, 1899.

Application filed April 13, 1898. Serial No. 677,429. (.No model.)

T0 all whom it may concern.'

Be it known that we, EDMUND S. WHITA- KER and JOHN CHADWICK, of the city of Providence, in the county of Providence and State of Rhode Island, have invented a certain new and useful Improvement in Cap- Spindles; and we hereby declarethat the following is a l'ull, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

The invention has reference to an improvement in the class of spinning-spindles used on cap-spinning machines in which the spindle is stationary and the bobbin while rotating on the spindle is made to move longitudinally on the spindle.

The invention consists in the peculiar and novel construction and combination of -the oiling device and the stationary spindle and bobbin-supportpas will be more fullyset forth hereinafter.

Figure 1 is a vertical sectional view of the bobbin-support, showing the same in connection with a dead-spindle. Fig. 2 is a transverse sectional view of the bobbin-support on the line AA of Fig. 1. Fig. 3 is a transverse sectional view of the bobbin-support on the line B B of Fig. 1. Fig. 4 is a perspective view oi' the dowel-ring. Fig. 5 is a side View of the oil-chamber. Fig. 6 is atop View, partly in section, of the oil-chamber. Fig. 7 is a transverse sectional View of the oil-chamber. Fig. 8 represents in perspective the bridge a, supporting the wick b and the clamp c in the oil-chamber, by which the oil is raised from the oil-chamber and is delivered to the spindle.

In the drawings, 8 indicates the stationary or dead spindle; 9, the reciprocating rail 10, the oil-chamber; 11, the cover of the oil-chamber; 12, the whirl; 13, the Vtube extending through and above the whirl, over which the bobbin is placed; 14, a clamp-ring secured to the dovetailed dowels 14', extending above the top surface of the Whirl. The clamp-ring 14: is provided with the dowels 142 142, which enter the base of the bobbins in place of the usual dowels, so that when the dowels are worn a new ring may be clamped on the dovetailed dowels 14. By inserting these into the recesses 143 the spring of the open ring will secure the same firmly.

The internal diameter of the tube 13 is greater than the diameter of the dead-spindle 8, and a series of oil-chambers 15 15 are formed by securing within the tube 13 the bushings 1G and 16', one at the lowerand one at the upper end of the whirl, and above the whirl the bushings 162 and 163 are made of short sections of tube having frictional contact with the spindle and being secured to the inside of the tube 13. In the reciprocation of the tube the bushings act as wipers and prevent the accumulation ot' oil on the spindle, while the intermediate spaces 15 between the bushings act in-reciprocating to distribute the oil on the spindle and insure its thorough lubrication. -The oil-chamber 10 has the centrallylocated and externally-threaded tube 17 extending upward to or slightly above the oil in the oil-chamber. The internally-screwthreaded annular ring 18 secures the packing-ring 19, made of cork, felt, or other similar material, to the end of the tube 17.

The bridge a in Fig. 8 consists of a sheet of metal having the flanges a a', the slits @2rd, and the opening 0.3 for the spindle. The strip of wicking b has also the central hole 0.3. lt is placed on the bridge ot, and the ends are extended through the slits a2 into the oil of the oil-chamber, as shown in Fig. 7, so that the oil is raised by capillary attraction and conveyed to the spindle. The clamp c consists in a sheet-metal ring and two strips of sheet metal on opposite sides ot' the ring. It is used to secure the wicking b to the bridge by bending the strip c' under the same. The washer 20 is placed between the lower end of the whirl 12 and the clamp c. The cover 11 has the two sectional flanges 11 11', one of which is provided with a stop-pin which eX- tends outward through an opening 21 in the side of the oil-chamber, through which the oil is supplied to the oil-chamber, and then the openin g is closed by the partial rotation ofthe cover 11.

By this construction the tube forming the bobbin-support rotates freely on the deadspindle. Each one of the bushings distributes the oil evenly on the spindle and carries any surplus oil upward and downward on the spindie, thereby insuring the thorough lubrication of all the bearings, while the oil in being IOO drawn upward from the oil-chaniberis ltered by the wick.

HavingY lLilus described our invention, we claim as new and desire to secure by Letters Patent- 1. In a lubricating device for cap-spinning machines, the combination with the oil-chainber 10, the cover 11, the central tube 17, l(he packing-ritmi,r 19, and the annular ring 1S, of the bridge a having the slits d2 co2 and the opening a3, the wick b the ends of which are passed through l[he slits in the bridge, and the clamp c, substantially as herein shown and described.

2. In acari-spinning machine, the combination with the dead-spindle, Lhe reciprocating EDMUND S. WHITAKER. JOHN CHADVVICK.
